"""hooks/on_init with buttons
In this example, on_init is used to configure callback on button 'b=ciao'
that is only present in the mask that will pop up if you right click on a row
Registering a hook
------------------
note that here we have registered the hook rather than passing it to the
sqlwidget. The advantage is that it will be used by *any* widget that is
created. Of course you should be carefull in using this feature as any
contraints will be enforced in any sqlwidget of that table.
When registering a hook or a layout you can mask it with a nick and use
layout_nick when calling it.
